Hard to fathom that ability to protect such high energy circuits, from
faults...
Kind of like the Master swordsman from Japan who worked with Tom Cruise, and
was able to contain his very high energy delivery
of a sword swing, when Tom Cruise' "horse" faulted at precisely the WRONG
moment in the filming of Last Samurai
They say a real Samuraii Sword handled by an expert was able to completely cut
a guy.... well you get the picture...
The Movie delivery of the high energy samauri sword swing aimed at Cruise'
neck, by the true master was on it's way when Cruise did not "duck" in time.
Only the complete control and skill by the real world master of samauri swords
prevented an awful headline the next day.
In the 60s and 70s, at the Navy Postgrad School, the ham club station was next
to a all metal shell, lab building
that I, as a kid ham, noticed had all kinds of warning signs outside the entry
doors.
Keep out High Voltage, Danger, Ear Protection Required, No Admittance,
Experiment in progress, etc etc...
Once iin a while, we hams heard what we thought were LOUD gunshots inside,
accompanied by flashes
of brilliant light you could see through the frosted glass windows.
Turns out they were discharging HUGE power supplies Many KV and many uF.
through teeny tiny wires, like
30 gauge.... The resulting explosions,BIG BANGS, EMP, and Plasmas generated
were what they were studying.
Judging from the era, and my later curiosity about EMP associated with Nuke
explosions, my bet is they were
studying EMP in great detail. One of the techs there told me back then, that
you could destroy practically every electronic
device in a house, by simply hanging a wire encircling the house and
discharging a big capacitor through it.
They had a whole library of books, titled and detaiing "Exploding wires" ,
with high speed photos of the various "loads"
vaporizing, mere microseconds after, say 30KV, 400uf short circuits.
I guess it was good that our NPS ham shack gear at the time was Collins S-Line,
and not new Solid State Rigs.
All the Best, 73,
